Full Story

Anthropic has closed one of the largest private funding rounds in AI to date. The company raised $13 billion in a Series F round that values it at $183 billion post-money.

The round was led by ICONIQ, with Fidelity Management & Research Company and Lightspeed Venture Partners joining as co-leads. A wide group of new and existing investors also took part, including Altimeter, Baillie Gifford, BlackRock-linked funds, Coatue, General Catalyst, GIC, Insight Partners, Ontario Teachers’, Qatar Investment Authority, TPG, T. Rowe Price, and others.

Anthropic’s CFO Krishna Rao said customers are leaning heavily on the company’s models for real work. He said demand is rising fast across large companies, startups, and developers, and that the new funding shows strong confidence in how the business is performing.

The company has grown quickly since launching its Claude chatbot in March 2023. By early 2025, Anthropic was already running at about $1 billion in annualized revenue. By August 2025, that figure had crossed $5 billion, just eight months later.

Anthropic now works with more than 300,000 business customers. The number of large clients, each bringing in over $100,000 a year, has jumped nearly seven times in the past year.

Much of the recent growth has come from Claude Code, a developer-focused product launched fully in May 2025. The tool has already crossed $500 million in run-rate revenue, with usage climbing sharply in a short time.

ICONIQ partner Divesh Makan said Anthropic stands out for pairing strong research with a clear focus on customers. He added that many enterprise leaders see Claude as dependable and built with long-term responsibility in mind.

Anthropic said the new capital will go toward meeting enterprise demand, expanding safety research, and pushing further into global markets.
